[QUOTE="Dan B, post: 1035828, member: 71978"] Hi all, another power steering pump question. My trac's original PS pump, going on 140K miles, developed a whine when I first start the engine and it is cold. The whine would last for about 5 minutes or so until everything warmed up. Tired of this, I purchased a Cardone reman pump. Before I went ahead with the install, I removed as much old fluid as I could by running the old pump with the return line disconnected from the reservoir and directed into a bucket while adding new STP "Multi-purpose ATF" to the reservoir, which is what it currently is filled with now. I installed the new pump, tried to hand prime it and then gave it a go. Same exact symptoms as the old pump, loud as hell until it warms up then it's fine. I know everyone says "Ford pumps are loud" but this was never a problem until recently. I guess my questions are, 1- did I screw up the fluid and need Mercon ATF? 2- regardless of fluid, does this indicate a bad reman pump since the old pump did the exact same thing? 3- Anything else I could do to quiet this down? The reservoir has some junk built up on the screen I can't remove but not enough that would cause blockage. I'm certain it is the pump making noise, not something else. The pump only cost $30 but still, I'd hate to ruin this new pump and have to replace it yet again. Thanks for any help, Dan B. [/QUOTE]
